USPP18209P2 - Anigozanthos plant named ‘Rambueleg’ - Google Patents

Abstract

A new and distinct cultivar of Anigozanthos plant named ‘Rambueleg’, characterized by its compact, upright and outwardly spreading plant habit; freely and early flowering habit; freely branched flowering stems; and large red purple-colored flowers.

Description

Botanical designation: Anigozanthos flavidus.

Cultivar denomination: ‘Rambueleg’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anigozanthos, botanically known as Anigozanthos flavidus, commonly referred to as Kangaroo-Paw, and hereinafter referred to by the name ‘Rambueleg’.

The new Anigozanthos is a product of a planned breeding program conducted by the Inventor in Tuggerah, New South Wales, Australia. The objective of the breeding program is to create new compact Anigozanthos cultivars that are suitable for container production, are freely flowering and have bright flower coloration.

The new Anigozanthos originated from a cross-pollination made by the Inventor on May 11, 1998 in Tuggerah, New South Wales, Australia of a proprietary selection of Anigozanthos flavidus identified as code number H80, not patented, as the female, or seed, parent with the Anigozanthos flavidus cultivar Flashpoint, not patented, as the male, or pollen, parent. The new Anigozanthos was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Tuggerah, New South Wales, Australia.

Asexual reproduction of the new Anigozanthos by in vitro propagation of micro-plants in Tuggerah, New South Wales, Australia since June, 1999, has shown that the unique features of this new Anigozanthos are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Rambueleg’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Rambueleg’. These characteristics in combination distinguish ‘Rambueleg’ as a new and distinct cultivar of Anigozanthos:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Freely and early flowering habit.
  • 3. Freely branched flowering stems.
  • 4. Large red purple-colored flowers.

Plants of the cultivar ‘Rambueleg’ can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos and the female parent selection differed in the following characteristics:

• • 1. Plants of the new Anigozanthos had brighter green-colored leaves than plants of the female parent selection.
  • 2. Plants of the new Anigozanthos were more freely branching than plants of the female parent selection.
  • 3. Plants of the new Anigozanthos had longer flowering stems than plants of the female parent selection.

Plants of the cultivar ‘Rambueleg’ can be compared to plants of the male parent, the cultivar Flashpoint. In side-by-side comparisons conducted by the Inventor in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos and the cultivar Flashpoint differed in the following characteristics:

• • 1. Plants of the new Anigozanthos had shorter leaves than plants of the cultivar Flashpoint.
  • 2. Plants of the new Anigozanthos had bright green-colored leaves whereas plants of the cultivar Flashpoint had variegated foliage.

Plants of the new Anigozanthos can be compared to plants of the cultivar Bush Garnet, not patented. In side-by-side comparisons conducted in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos differed from plants of the cultivar Bush Garnet in the following characteristics:

• • 1. Plants of the new Anigozanthos were more compact than plants of the cultivar Bush Garnet.
  • 2. Plants of the new Anigozanthos had longer leaves and flowers than plants of the cultivar Bush Garnet.
  • 3. Plants of the new Anigozanthos flowered earlier than plants of the cultivar Bush Garnet.

Plants of the cultivar ‘Rambueleg’ can also be compared to plants of the cultivar Bush Ranger, disclosed in U.S. Plant Pat. No. 6,478. In side-by-side comparisons conducted by the Inventor in Tuggerah, New South Wales, Australia, plants of the new Anigozanthos and the cultivar Bush Ranger differed in the following characteristics:

• • 1. Plants of the new Anigozanthos were taller than plants of the cultivar Bush Ranger.
  • 2. Plants of the new Anigozanthos had longer leaves and flowers than plants of the cultivar Bush Ranger.
  • 3. Flowers of plants of the new Anigozanthos were more red than flowers of plants of the cultivar Bush Ranger.
